Services

My Services

I work with teams and founders to design, build and ship software — from a single feature to a complete product.

01
Web Applications

Full-stack products, from first commit to production. A production-ready application your team can keep building on.

02
Frontend Engineering

Interfaces that feel fast and hold up under real use. A polished interface that is consistent, accessible and easy to extend.

03
Backend & APIs

Reliable services and clean contracts. A backend you can trust with real traffic and real data.

04
E-commerce

Storefronts that are fast, custom and easy to run. A store that loads quickly and makes buying straightforward.

Performance & SEO

Faster pages, better rankings. Measurably faster pages and sustainable organic traffic.

06
DevOps & Delivery

Ship often, without drama. A release process the whole team can rely on.

How it works

Simple process,
exceptional results.

Step 01Discovery

A short call to understand your goals, constraints and timeline, and to decide whether I am the right fit.

Book a call
Step 02Proposal

A clear written scope with milestones, pricing and timeline, so there are no surprises once work begins.

Start a project
Step 03Build & hand-off

Iterative delivery with regular demos, then a documented hand-off. You own the code and everything in it.
